Figure 3.

Airway subepithelial collagen and smooth muscle layer thickness unchanged in Cav1^-/- mice. Morphometric quantification of Collagen1 (A) and Collagen3 (B) immunostaining. Error bars indicate SEM. Significance was determined by ANOVA followed by a Tukey’s post test. (C) Morphometric analysis of thickness smooth muscle cell layer in Cav1^-/- and WT mice as they age. n = 14-21. Error bars indicate standard error. Significance determined by Student’s T test between age matched in Cav1^-/- and WT mice.
